Kusankha kabowolere koyenera ka polojekiti yanu kumaphatikizapo kumvetsetsa zinthu zitatu zofunika: zinthu, zokutira, ndi mawonekedwe a geometric. Chilichonse mwazinthu izi chimagwira ntchito yofunika kwambiri pakubowola komanso kulimba kwake. Pano pali kuyang'anitsitsa momwe mungapangire chisankho mwanzeru.
Zakuthupi
1. Chitsulo Chothamanga Kwambiri (HSS):
High-Speed Steel (HSS) yakhala yofunikira pazida zodulira kwazaka zopitilira zana, zomwe zimayamikiridwa chifukwa chakugwiritsa ntchito kwake komanso kukwanitsa kukwanitsa. Mabowo a HSS amadziwika chifukwa cha kusinthasintha kwawo, amachita bwino ndi kubowola kwa manja ndi nsanja zokhazikika monga makina osindikizira. Ubwino waukulu wa HSS ndikunolanso, kukulitsa moyo wautali wazobowola ndikupangitsa kuti ikhale yotchipa kusankha zida za lathe. Kuphatikiza apo, HSS ili ndi magiredi osiyanasiyana, iliyonse ili ndi zolemba zosiyanasiyana kuti zikwaniritse zosowa zapadera. Kusiyanasiyana kumeneku m'makalasi achitsulo kumawonjezera kusinthika kwa HSS, ndikupangitsa kuti ikhale yosunthika komanso yofunika kwambiri pantchito zosiyanasiyana zamakina.
2. Cobalt HSS (HSSE kapena HSSCO):
Poyerekeza ndi HSS yachikhalidwe, Cobalt HSS imawonetsa kuuma kwapamwamba komanso kupirira kutentha. Kupititsa patsogolo kwazinthu izi kumapangitsa kuti ma abrasion asamayende bwino, zomwe zimapangitsa kuti ma HSSE kubowola azikhala olimba komanso ogwira mtima. Kuphatikizika kwa cobalt mu HSSE sikumangowonjezera kukana kwake kuphulika komanso kumawonjezera moyo wake wonse. Mofanana ndi HSS wamba, ma bits a HSSE amakhalabe ndi phindu lakuthwanso, zomwe zimakulitsa moyo wawo wogwiritsiridwa ntchito. Kukhalapo kwa cobalt mu HSSE kumapangitsa kuti tizidutswa tating'ono ting'onoting'ono timene tigwire ntchito zovuta kwambiri zobowola pomwe kulimba komanso kukana abrase ndikofunikira.
3. Carbide:
Carbide ndi chitsulo chophatikizika chachitsulo, chopangidwa makamaka ndi tungsten carbide yokhala ndi zomangira zosiyanasiyana. Imaposa kwambiri HSS mu kuuma, kupirira kutentha, ndi kukana abrasion. Ngakhale okwera mtengo, zida za carbide zimapambana pa moyo komanso kuthamanga kwa makina. Amafuna zida zapadera zonoleranso.
Kupaka
Zovala za Drill bit zimasiyana mosiyanasiyana ndipo zimasankhidwa kutengera ntchito. Nawa mwachidule za zokutira wamba:
1. Osakutidwa (Wowala):
Ndiwo mtundu wodziwika kwambiri wa ma HSS drill bits. Zoyenera pazida zofewa monga ma aluminiyamu aloyi ndi chitsulo chochepa cha carbon, zida zopanda utoto ndizotsika mtengo kwambiri.
2. Kupaka kwa Black Oxide:
Amapereka mafuta odzola bwino komanso kukana kutentha kuposa zida zosaphimbidwa, ndikuwongolera moyo wawo ndi 50%.
3. Kupaka kwa Titanium Nitride (TiN):
Zobowola zokutidwa ndi titaniyamu zimagwira ntchito bwino pamawonekedwe ambiri ogwiritsira ntchito chifukwa cha mawonekedwe awo apadera. Choyamba, Imakulitsa kuuma ndi kukana abrasion kudzera pakupaka, kulola pang'ono kukhala yakuthwa ndikubowola zida zolimba, ndikupereka moyo wautali wautumiki. Tizidutswa tating'onoting'ono timachepetsa kukangana ndi kutentha, ndikuwonjezera kudula bwino ndikuteteza pang'ono kuti zisatenthedwe. Titaniyamu yokhala ndi titaniyamu ndi yoyenera kugwiritsidwa ntchito pazinthu zambiri, monga zitsulo zosapanga dzimbiri, aluminiyamu ndi matabwa, zomwe zimapangitsa kuti zikhale zabwino kwambiri paukadaulo ndi ntchito zapakhomo. Kuphatikiza apo, tizidutswa tating'ono tating'onoting'ono timalowa m'zinthu mwachangu komanso mwaukhondo, zomwe zimapangitsa kuti pakhale malo odulira bwino. Ngakhale kubowola kwa titaniyamu kumatha kuwononga ndalama zambiri kuposa zobowoleza nthawi zonse, kuchita bwino kwambiri komanso moyo wautali zimawapangitsa kukhala obweza ndalama pazantchito zomwe zimafuna kukana kwambiri abrasion ndi kudula ndendende.
4. Kupaka kwa Aluminium Titanium Nitride (AlTiN):
Choyamba, zokutira za AlTiN ndizosamva kutentha kwambiri, zomwe zimawathandiza kuti azitha kuchita bwino kwambiri pakudula komanso kukonza ma alloys otentha kwambiri. Kachiwiri, ❖ kuyanika uku kumathandizira kwambiri kukana kwa abrasion ndikukulitsa moyo wa zida, makamaka popanga zida zolimba monga chitsulo chosapanga dzimbiri, ma aloyi a titaniyamu ndi ma aloyi opangidwa ndi faifi tambala. Kuphatikiza apo, zokutira za AlTiN zimachepetsa kukangana pakati pa kubowola ndi chogwirira ntchito, kukonza makina ogwirira ntchito komanso kuthandiza kuti pakhale malo odulira bwino. Ilinso ndi kukana kwa okosijeni wabwino komanso kukhazikika kwamankhwala, zomwe zimawathandiza kuti azigwira bwino ntchito m'malo ovuta. Ponseponse, zobowola zokhala ndi AlTiN ndizoyenera kugwiritsa ntchito makina othamanga kwambiri, olondola kwambiri, ndipo ndi oyenerera makamaka kugwiritsira ntchito zida zolimba zomwe zimabweretsa zovuta pakubowola wamba.
Mawonekedwe a Geometric
1. Utali:
Chiŵerengero cha utali ndi m'mimba mwake chimakhudza kusasunthika. Kusankha pobowola yokhala ndi kutalika kwa chitoliro chokwanira kuti chip chisamuke komanso kuchulukira pang'ono kungapangitse kulimba komanso moyo wa zida. Kusakwanira kwa chitoliro kumatha kuwononga pang'ono. Pali mitundu yosiyanasiyana yautali yomwe mungasankhe pamsika. Utali wina wodziwika bwino ndi Jobber, stubby, DIN 340, DIN 338, etc.
2. Drill Point angle:
Mbali ya 118 ° ndiyofala pazitsulo zofewa monga chitsulo chochepa cha carbon ndi aluminiyamu. Nthawi zambiri ilibe luso lodzidalira, imafunikira bowo loyendetsa. Mbali ya 135 ° point, yokhala ndi mawonekedwe ake okha, imachotsa kufunikira kwa dzenje lapakati, kupulumutsa nthawi yofunikira.
Pomaliza, kusankha chobowolera chopindika choyenera kumaphatikizapo kulinganiza zofunikira za zinthu zomwe zikubowoledwa, moyo womwe mukufuna komanso momwe kagwiritsidwira ntchito, komanso zofunikira za polojekiti yanu. Kumvetsetsa zinthu izi kuonetsetsa kuti mukusankha kubowola kothandiza komanso kothandiza kwambiri pazosowa zanu.
